Management of Rust disease in Wheat

20/01/2020Posted on
    • Leaf rust is caused by the fungus.
    • The first signs of the disease (sporulation) occur 10-14 days after infection
    • Leaf rust produces reddish-orange coloured spores which occur in small, 1.5 mm, circular to oval-shaped pustules.
    • These are found on the top surface of the leaves, distinguishing leaf rust from stem rust which is found on both surfaces of the leaf.
    • The spores require 15 to 20ºC temperature and free moisture (dew/rain/irrigation) on the leaves to successfully infect wheat.

 

Management-

  • Crop rotation is very important.
  • Growing resistant varieties is an economical and environmentally friendly way of disease reduction.
  • During the growing season, active crop monitoring is very important for an early detection of diseases.
  • Avoid repeated use of fungicides with the same active ingredient.
  • Spray Kasugamycin 5% + Copper Oxychloride 45% WP 320 gm/acre or Propiconazole 25% EC 240 ml/acre.

Application of Manure and fertilizers in Garlic

18/01/2020Posted on

Garlic can be grown in almost all types of soil, however sandy, slit and clay loamy soil are best for cultivation, however it can also be grown in clayey soil. In heavy clay soil garlic should be planted in raised beds. Soil should be well drained and should be capable of holding water during the growth phase. Ideal pH should be 6 – 7.5 with high nitrogenous fertilizers @ 40 kg/.acre for early vegetative, phosphorus @ 20 kg/acre for better root development, potassium @ 20 kg/acre for critical leaf development and bulb formation. Pungency in garlic is because of good sulfur content.  Sulfur should be given @ 20 kg/acre after plants  have come out and leaf development has started for better pungency. Also mix the FYM at the @ 4-6 tonnes /acre at the time of preparation of the soil.

Nutrient management of Tomato

04/01/2020Posted on
  • Tomato needs a heavy dose of fertilizers for a good yield.
  • Farmyard manure @ 8-10 tonnes/Acre may be incorporated into the soil one month before transplanting.
  • DAP 50 kg/Acre, Urea 80 kg/Acre and MOP 33 kg/Acre.
  • Full amount of DAP, MOP and half of Urea are to be added just before transplanting.
  • Rest of the Urea is to be given as a second dose at 20-25 days after transplanting, and third dose is given at 45-60 days after transplanting.
  • Zinc sulphate application (Znso4@10 kg/Acre) and Boron 4 Kg/Acre increases yield as well as improves the quality of fruit.

  • Maize cultivated during the monsoon, winter and spring season.

  • Therefore at 1-2 weeks interval depending on rainfall and temperature.
  • For different water availability scenario, the irrigation scheduling can be as follow-
  • If five irrigations available apply at 1.) Six leaf stage, 2.) Late knee-high stage, 3.) Tasseling stage, 4.) 50% silking stage and 6.) Dough stage.
  • If three irrigations available apply at 1.) Early knee-high stage, 2.) Tessling stage and 3.) 50% silking stage.

Control of Root Aphid in Wheat

03/01/2020Posted on
  • This insect is active from November to February.
  • Damage is more in rainfed and late sown crop.
  • Yellowing of young plants is observed due to root aphids. In this case minute yellowish brown aphids may be present near the base or on the roots of the plant.
  • Aphids also vector a viral disease named barley yellow dwarf virus (BYD). Yield of infected wheat plants can be reduced by 50%.

Control-

  • Avoid late sowing.
  • Avoid use excess nitrogen fertilizers.
  • If the infestation in standing crop, Spray imidacloprid 17.8% SL @ 60-70 ml/acre.
  • Or apply thiamethoxam 25% WG @ 100 gm/acre in soil with fertilizer/Sand/soil before irrigation.
